Activities at the Geometry Center

Dr. Sullivan's research centers on finding optimal geometric structures,
such as minimal surfaces, Willmore surfaces, and energy-minimizing knots.
He is also interested in computational issues related to such problems.

Recently, Dr. Sullivan has been involved in the
Laterna MatheMagica
project, in which a sphere is everted via the Willmore flow.
He has made several computer graphics
images of soap films.
Around 1988, he wrote a program
vcs to compute voronoi diagrams in
three dimensions.
In 1995, he wrote a java program demonstrating
stereographic projection.
